O que é o host 'play'?

Question

Eu testei o seguinte em uma máquina Ubuntu.

O comando

ping play

resulta em

PING play (127.0.53.53) 56(84) bytes of data.
64 bytes from 127.0.53.53: icmp_seq=1 ttl=64 time=0.029 ms
64 bytes from 127.0.53.53: icmp_seq=2 ttl=64 time=0.036 ms
64 bytes from 127.0.53.53: icmp_seq=3 ttl=64 time=0.032 ms
64 bytes from 127.0.53.53: icmp_seq=4 ttl=64 time=0.030 ms

Se eu fizer o seguinte:

ssh play

Eu posso fazer login na minha própria máquina localhost .

Finalmente, o seguinte:

dig play

Resultados em:
